Patent number: 9642239Abstract: A conduction cooling system for linear accelerator cavities. The system conducts heat from the cavities to a refrigeration unit using at least one cavity cooler interconnected with a cooling connector. The cavity cooler and cooling connector are both made from solid material having a very high thermal conductivity of approximately 1×104 W m?1 K?1 at temperatures of approximately 4 degrees K. This allows for very simple and effective conduction of waste heat from the linear accelerator cavities to the cavity cooler, along the cooling connector, and thence to the refrigeration unit.Type: GrantFiled: April 17, 2015Date of Patent: May 2, 2017Assignee: Fermi Research Alliance, LLCInventor: Robert Kephart
